Using the CLI To Configure a Static or Dynamic Trunk
Group
Important Configure port trunking before you connect the trunked links between
switches. Otherwise, a broadcast storm could occur. (If you need to connect
the ports before configuring them for trunking, you can temporarily disable
the ports until the trunk is configured. See
“Using the CLI To Configure Ports”
on page 10-8.)
On the Series 5300XL Switches you can configure up to 36 port trunk groups
(depending on the number of ports available in the switch and the number of
links in each trunk). An individual trunk can have up to eight links, with
additional standby links if you’re using LACP. You can configure trunk group
types as follows:
Trunk Type Trunk Group Membership
TrkX (Static) DynX (Dynamic)
LACP Yes Yes
Trunk Yes No
FEC Yes No
The following examples show how to create different types of trunk groups.
